PNF F-16 Fighting Falcon EDF 550mm Instruction Manual

1. You now need to check that the gyro is functioning correctly.

2. Move the gyro switch down into the "Training Mode", this is the switch in the fully down position.

Now smartly roll the wings left and right, you should then see the ailerons moving in the opposite

direction to the rolling moment. Then smartly pitch the nose of the plane up and down, you should

then see the elevator servo moving the elevator in the opposite direction of the pitching. If you find

it difficult to see which way a surface is moving, gently hold the surface, then as you move the

model, you should be able to feel the servo moving in the opposite direction. When the gyro is in

"Training Mode" this limits the amount of roll, and pitch, you can subject the model to. You can put

a full control command in, and the model will only respond up to a certain angle. Also this mode

will self right the model if it starts to spiral out of control. Just let go of the sticks, close the throttle,

and the gyro will do the rest.

3. With the switch is in the middle position, "Gyro On" , perform the same actions as above, the

servos will still move but to a lesser degree. In this mode the gyro will still be assisting your flying

and helping smooth things out, but it does not limit the roll, and pitch angles, nor will it self right as

quickly. In this mode you will be able to perform simple aerobatics when you are ready.

4. Now put the switch into the "Gyro Off" position, now when you perform this test, the servos

should not move at all. So in this mode you will get no gyro assist at all, this mode is only for

experienced fliers.

5. Once these checks are complete, leave the transmitter switched on and disconnect the flight

battery. Once the battery has been disconnected you can then turn off the transmitter. Never have

the flight battery plugged in and the transmitter switched off, this is dangerous.

6. So a quick recap on the switching on, switching off process. Always switch the transmitter on

first and check that the switches, trims and throttle stick are in their correct positions, only then

plug in the flight battery. Once you have finished testing or flying, disconnect the flight battery first,

and only then switch off the transmitter.
